Abstract

(A) Cpds. of the general formula (I) R = H or (2-7C) lower alkanoyl (B) Salts of I. Sedatives. 4.69N NaOEt/MeOH (0.9 ml) was added to III (1 g.) in DMF (15 ml), stirred 0.5 h., and ethylene oxide (0.45 g.) in DMF (5 ml) added. The mixture was stirred 2 h. at 25 deg., 1 h. at 60 deg., evapd. in vac., and succinic anhydride (1.5 g.) in PhMe (50 ml) added. After refluxing 3 h., the mixture was cooled in ice, basified (NH4OH) and sepd. The H2O phase was treated with 3N-NaOH (5 ml), stirred 30 mins., acidified (cHCl), and basified (NH4OH), extd. with CH2Cl2, washed with brine (50 ml), dried and evapd. The residue in PhH (15 ml) was filtered through SiO2 (50 g), eluted with PhH (200 ml) and EtOAc (250 ml), the EtOAc evapd., dissolved in EtOH (5 ml), and HCl-EtOH added, giving I-HCl (R=H), m.p.195-7 deg.
